Nero 3 Avenger Pump Cover

A 3D printed replacement pump cover for AI Nero 3 owners who want more control over flow behavior while protecting sensitive reef livestock.

• Nero 3-specific fit: Built as a direct replacement part rather than a generic aquarium accessory.
• Three flow-pattern options: Lets reef keepers tune circulation for different coral placement and tank conditions.
• Integrated nem guard: Helps reduce risk around anemones and other delicate inhabitants.
• Designed to look intentional: Adds a cleaner printed upgrade instead of leaving the pump as a plain stock component.

A more polished storefront version of the original listing, with the same reefing function preserved.
